Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a high frequency electric scalpel device.

[Prior Art] In a conventional high-frequency electric scalpel device, when setting the high-frequency output level, a setting dial is operated and, for example, ○9 is set.
The output is set at the middle of the 5 scales.

[Problem to be Solved by the Invention 1] In the conventional electric scalpel device as described above, the daily unit is large and it is not possible to set the tip in detail. Doctors who actually use high-frequency electric scalpels want to be able to set the output finely when making fine incisions due to low output, and for this reason, it is required to be able to set the output in fine scales of about 0.1 scale. There is. However, if the output level is changed step by step on a fine scale, it takes a long time to set a high setting value, which hinders the speed of treatment using an electric scalpel.

Therefore, it is an object of the present invention (j) to provide a high-frequency electric scalpel device in which the set value range is changed around a predetermined set value.

[Function] According to the present invention, there is provided a high-frequency output generating section that generates the high-frequency 114 force for treatment and a setting section that sets the output level of the high-frequency output generating section, and the set value range is coarse and fine with a predetermined set value as the boundary. By being able to set the output level precisely at low output levels, the output level can be set quickly and safely at high output levels.

[Embodiment] According to the high-frequency electric scalpel device shown in FIG. 1, a connector portion 11 and a switch portion 12 are disposed vertically separately. ] The connector part 11 has a check word connector 13 for connecting a check lead when checking the output.
, Connector 1 for connecting the bipolar electrode plug
4. A hunt switch (= connector 15 for connecting the plug of the J female holder, connector 16 for connecting the coat plug to the connector), and connector 17 for connecting the S-P cord or P cord are provided. .

The switch display section 12 is provided with switches 180 and 181 for adjusting the up-down output of the cutting current or mixed current. 'yW selection switch 19 is provided to select either cutting or mixing. By selecting the output 3.4 by the selection switch 19, the incision display I-"[20 and] kneading display river 1-"[21] is lit. The power levels are adjusted by switch 23D and switch 23U.The cutting and mixing power levels are indicated by numerical display segments 1-25, and the coagulation power levels are indicated by numerical display segments 1-26.

The circuit of the above-mentioned high frequency electric scalpel device is schematically constructed as shown in FIG. According to this, switches 18D, 181, 19.22.23D, 23
A key human power unit 31 including 1 is connected to a micro processor (MPU) 32. MPU 32
(, lI; Amplifier (ΔMP) 3 via output editing unit 33
Connected to 4.

The output control unit 33 is configured to control the high frequency output level (to 1 as described later).
It is connected to a display unit 35 including 25 and 26.

Next, the operation of the high-frequency electric scalpel device will be explained with reference to flow steps p-l~ in FIG. For example, when the switch 19 is pressed to set the incision mode, the incision display IFD 20 lights up and the incision mode is displayed.

Here, first, it is checked whether the output setting value in the current state, that is, the current data is equal to the highest level of 10.0. If the current data is not 10.0, it is checked whether the current data is 2.5 or more. If it is 2.5 or more, 0.5 is added to the current data and updated to new current data. At this time, a sound will be played to notify you of the level up. This sound is played for 0.5 seconds. After 0.5 seconds have elapsed, the process returns to the first flow, that is, the key operation flow. At this time, if the key remains pressed, 0.5 is further added to the current data and an UP sound is sounded. In this way, the output level is increased in 0.5 increments.

If the current data is less than 2.5, 0°1 is added to the current data and updated as new current data. At this time as well, the UP sound is sounded. Next, the current data is divided by 0.5, and it is determined whether the remainder is ○ or not. If the remainder is ○, the process returns to the key-on check flow after 0.35 seconds have elapsed, and as long as the key is on, the current data is updated in units of 0.1.

If the remainder is not ○, the key-on check flow returns after 0.2 seconds and the current data is 0 as long as the key is on.
．． Updated in units of 1.

As mentioned above, with 2.5 as the predetermined setting value, this setting value 2
．． For a set value of 5 or more, the high frequency output level is varied at 0.5 level intervals and after 0.5 seconds, and for a set value of less than 2.5, the high frequency output level is varied at 0.1 intervals. Output level can be changed.

In this case, when the set value is less than 2.5, it is varied every 0.2 seconds, but when it reaches 2.5, the set value is updated after 0.35 seconds have elapsed.

As above, the high frequency output value is increased continuously,
The output adjustment stops when the desired value is obtained and the key is turned off. Further, when the set value reaches 10.0, the output increase is stopped so that the high frequency output does not rise above this value.

When the high frequency output level is set to a desired value, the set level at that time is displayed numerically on the display segment 25 of the display section 35. This setting value data is MPU 3
2, the MPU 32 controls the output control unit 3 so that a high frequency cutting output at a level corresponding to the set value is obtained.
Control 3. As a result, the output control section 33 outputs a high frequency cutting signal corresponding to the cutting output. This high frequency cutting signal is input to the ΔMP 34 and amplified, whereby a high frequency cutting current having a desired set value is outputted via the connector 17. The affected area is incised by applying this high frequency cutting current to the affected area via the high frequency knife.

The operation of the high-frequency electric scalpel device shown in FIG. 4 will be explained. The continuous flag is set to 1 when the output up key 180 is not turned on. When the key switch 181 is turned on, it is checked whether the current data is 10.0. If less than 10.0, continuous flag or 1
It is checked whether or not. If the flag is not 1, the current data is returned to the old data. At this time, if the current data is 2.5 or more, 0.5 is added to the current data and the current data is updated. If the current data is less than 2.5, add 0.1 to the current data.
is added and the current data is updated in steps of 0.1. When the current data is updated, an UP sound is generated. After this, the current data is divided by 0.5, and it is determined whether the remainder is ○ or not. If the remainder is ○, the continuous flag is set to 1 after 0.35 seconds have elapsed. If the remainder is not O, the continuous flag is set to 1 after 0.2 seconds have elapsed. That is, the current data 10
The remainder of the division by 5 is determined by determining the transition from fine adjustment to coarse adjustment in steps of 0.1, and at this transition value the variable time is changed from 0.2 seconds to 0.35 seconds. This is designed to give time to consider the large output increase.

As explained in the above embodiment, in this invention, when the set value is lower than a predetermined value, for example, 2.5, the output is finely adjusted with a set width of 0.1 increments.
In the case of a set value greater than the predetermined value of 2.5, the output is adjusted by coarse adjustment with a set width of 0.5 (). At this time, the step up and step down of the set value is fine adjustment, that is, 0
．． In the case of medium adjustment, the time is updated relatively quickly at 0.2 second intervals, but in the case of coarse adjustment, that is, the adjustment in units of 0.5, the time is updated at a slower rate of 0.5 seconds than in fine adjustment.

By using such adjustment time intervals, it is possible to avoid a sudden increase in the output during coarse adjustment, and since the setting range is fine during fine adjustment, there is no major problem even if the speed of adjustment is increased. In the above example, a sound is generated every time the setting value is changed in both coarse and fine adjustment, but in fine adjustment, the sound is generated only at O value and 0.5 value, and no sound is generated at other values. The complexity caused by this may be avoided.

[Effects of the Invention] According to this invention, the adjustment range of the high frequency output level is changed coarsely and finely based on a certain value, so at output levels that require fine adjustment, the output can be adjusted very finely and safely treated with an electric scalpel. In addition, the output can be set quickly during coarse adjustment.

Details of the invention Description [Industrial Application Field 1] The present invention relates to a high-frequency electric scalpel device. [Prior Art] In a conventional high-frequency electric scalpel device, when setting the high-frequency output level, a setting dial is operated and the setting dial is set to 0, for example.
Output settings are performed in units of 5 scales. [Problems to be Solved by the Invention] In the conventional electric scalpel device as described above, the scale units are large and detailed output settings cannot be made. Doctors who actually use high-frequency electric scalpels want to be able to set the output finely when making fine incisions due to the low output, and for this reason, it is required to be able to set the output in fine scales of about 0.1 scale. There is. However, if the output level is changed step by step on a fine scale, it takes a long time to set a high setting value, which hinders the speed of treatment using an electric scalpel. Therefore, an object of the present invention is to provide a high-frequency electric scalpel device in which the set value range is changed around a predetermined set value. [Operation 1] According to the present invention, a high-frequency output generating section that generates a high-frequency output for treatment and a setting section that sets the output level of the high-frequency output generating section are provided, and the set value range can be coarsely and finely divided from a predetermined set value. By being able to change the output level, it is possible to make detailed output settings at low output levels, and to make settings quickly and safely at high output levels. [Example] According to the high-frequency electric scalpel device shown in FIG. 1, the connector section 11 and the switch section 12 are arranged vertically separately. The connector part 11 includes a check lead connecting connector 13 for connecting a check lead when checking the output.
Connector 14 for connecting a bipolar electrode plug
, a connector 15 for connecting the plug of the female holder with a hand switch, a connector 16 for connecting the cord plug, and a connector 17 for connecting the S-P cord or the P cord. The switch display section 12 is provided with switches 18D and 18(C) for adjusting the uptown output of the cutting current or the mixing current.The selection switches 3 to 19 select either cutting or mixing. The output selection by the selection switch 19 lights up the incision display LED 20 and the mixing display LED 21.The coagulation switch 22 is operated to obtain the coagulation output, and the coagulation output level is set by the switch 23D and the coagulation output level. Switch 23U
adjusted by. The cutting and mixing power levels are indicated by numeric display segment 1 to 25 and the coagulation power level is indicated by numeric display segment 26. The circuit of the high frequency electric scalpel device is schematically constructed as shown in FIG. According to this, switches 18D 118U, 19.22.23D, 23
The key input section 31 including U is a microprocessor unit h.
(MPU) 32. The MPU 32 is connected to an amplifier (AMP) 34 via an output control section 33. The output control section 33 is configured to control the high frequency output level as described later. MPU 32 is L for display
ED20, 2'l, 24 and numeric display segment 25.
It is connected to a display unit 35 including 26. Next, the operation of the high frequency -4 electric scalpel device will be explained with reference to flowchart 1 in FIG. For example, when one switch is pressed and set to incision mode, the LFD for incision display
20 lights up and the incision mode is displayed. Here, first, it is checked whether the output setting value in the current state, that is, the current arc is equal to the highest level of 10.0. If the current data is 10,0 and '+>, it is checked whether the current data is 2.5 or more. If it is 2.5 or more, 0.5 is added to the current data.
is added and updated to the new current arc. At this time, a sound will be played to notify you of the level up. This sound is played for 0.05 seconds. After 0.5 seconds have elapsed, the process returns to the first flow, that is, the key operation flow. At this time, if the key remains pressed, 0.5 is further added to the current data and an UP sound is sounded. In this way, the output level is increased in 0.5 increments. If the current data is less than 2.5, 0°1 is added to the current data and updated as new current data. The UP sound will also sound at this point. Next, set the current arc to 0.5
, and it is determined whether this remainder is 0 or not. The remainder is O
Then, after 0.35 seconds have passed, the process returns to the key-on check flow, and as long as the key is on, the current data is updated in units of 0.1. If the remainder is not O, it will return to the key-on check flow after 0.2 seconds and the current data will be 0 as long as the key is on.
．． Updated in units of 1. As mentioned above, with 2.5 as the predetermined setting value, this setting value 2
．． For the set value above 5JX, the high frequency output level is varied at 0.5 level intervals and after 0.5 seconds, and for the set value less than 2.5, the high frequency output level is varied at 0.1 interval. Output level can be changed. In this case, if the set value C is less than 2.5, it will be changed every 0.2 seconds, but only when it reaches 0.5, 1.0, 1.5, or 2.0, 0.35 seconds will elapse. Wait for the settings to be updated. As described above, the high frequency output value is increased continuously,
The output adjustment stops when the desired value is obtained and the key is turned off. Further, when the set value reaches 10.0, the output increase is stopped so that the high frequency output does not rise above this value. When the high frequency output level is set to a desired value, the next set level is displayed numerically on the display segment 25 of the display section 35. This setting value data is MPU 3
2, the IPU 32 controls the output control unit 33 to obtain a high frequency cutting output at a level corresponding to the set value. As a result, the output control section 33 outputs a high frequency cutting signal corresponding to the cutting output. This high frequency cutting signal is input to the AMP 34 and amplified to output a high frequency cutting current of a desired setting value via the connector 17. This high-frequency incision current acts on the central part through the high-frequency knife, whereby the central part is incised. The operation of the high-frequency knife scalpel device will be explained using the flowchart shown in FIG. The continuous flag is set to O when the output up key 18 ( ) is not turned on. If the key switch 18U is turned on, it is checked whether the current data is 10.0. If it is less than 10.0. It is checked whether the continuous flag is 1. If the flag is not 1, the current arc assigns the current data to the old data.
If it is 5 or more, 0.5 is added to the current data and the current data is updated. If the current data is less than 2.5, 0.1 is added to the current data, and the current data is updated in steps of 0.1. When the current data is updated, an UP sound is generated. After this, the current data is calculated by 0.5, and the remainder is O
It is determined whether or not. If the remainder is 0, the continuous flag is set to 1 after 0.35 seconds have elapsed. 0 if the remainder is not 0
．． The continuous flag is set to 1 after 2 seconds have elapsed. That is,
Judgment of the remainder when dividing the current data by 10°5 makes it easy to set the 015 increments even if the density adjustment is in 0.1 increments, and the change time is only when the current data is set in 0.5 increments. The interval is changed from 0.2 seconds to 0.35 seconds. After setting the continuous flag to 1, return to the key-on check flow and the current data is 10. ○If it is not completed yet, check the continuity flag. Here, if the continuity flag is 1, the current data and old data are compared, and if the current data is larger than the old data by 2 or more, the process returns to the key-on check flow so that the flag does not rise continuously any more. In this case, release the key once to set the continuous flag to 0, and then press the key -8= again to operate. This prevents the set value from becoming unintentionally large when the output is increased continuously. As explained in the above embodiment, in this invention, when the setting value is lower than a predetermined value, for example, 2.5, the protruding horn is adjusted by finely adjusting the setting width in units of 0.1, If the setting value is greater than the predetermined value 2.5, the setting value is 0.
5, the output is adjusted by rough adjustment. At this point, the step-up and step-down of the set value is finely adjusted, that is,
In adjustment in units of 0.1, updates are made relatively quickly at intervals of 0.2 seconds, but in coarse adjustments, that is, adjustments in units of 0.5, updates are made slower at 0.5 seconds than in fine adjustments. By setting the interval between the adjustment ribs in this manner, it is possible to avoid a sudden increase in the output in the coarse adjustment, and in the fine adjustment, even if the adjustment speed is increased because the setting range is fine, no major problem occurs. In the above example, a sound is generated each time the set value is changed in both coarse and fine adjustment, but the sound is generated only at the X, 0 value and the X, 5 value edge, and other values are silent and the sound is generated. You may try to avoid casual glances. [Effect of the invention] According to this invention, the adjustment range of the high frequency output level can be changed coarsely or finely based on a certain value. At output levels that require fine adjustment, the output can be adjusted quite finely using an electric scalpel. Treatment can be performed safely, and J-3 can be used for rough adjustment.
output can be set quickly. 4.
